I don't know David Brown, but I thought I'd give him a hand as his original "Animation.sit" stack had a couple of bugs in it. Like the fact that he didn't include any icons for the "Begin" button (the one with the "Stop" and "Go" icons which I added -- I apologize for the poor artwork) and the fact that the "Continuous" button didn't work due to the deletion of a "Wait 30" command. But all is restored and things now work wonderfully! Please support this stack with your shareware fee to David as it's (now) a pretty good stack. And, Dave, hope you don't mind that I altered the original stack. Of course, you get the credit not to mention additional shareware fees!

To use the stack properly (Dave was a little nebulous on this), first click on the "Do It!" button to see what happens with the HyperTalk script I generated! Then to create your own animation, erase my picture using the eraser tool, copy a smallish picture from a Clip art stack or one of your choosing, and paste it into the rectangle (The location of the rectangle is really not essential, it just makes things neater for this stack. You could place the picture anywhere on the card, since the "Do It!" button calls for the lasso tool and the picture is on the "Card" level--it will get selected no matter where it is). Then click on the "Continuous" or "Point to point" button. Then click the "Go" sign and follow the directions in the field below the picture you pasted. You should see HyperTalk script being generated in the field on the right. The next step is to click on the "Set up" button which transfers the script into the "Do It!" button's script. Then click "Do It!" and watch your animated picture go wild.
Oh yeah, you may notice that if you use a large picture such as the one I substituted, and if you specify a position too near the card's edges (the starting point being near the character's nose or near the middle of his head) that the stack draws lines instead of moving your picture around. This can be remedied by not going so near the edges with your clicking!
To utilize the animation in stacks of your own, simply make sure the picture is in the same relative position in your stack as the one in this stack. Then copy the "Do It!" button into your stack. Modify the "Do It!" button to your liking so that the name doesn't show and/or create your own icon button using ResEdit (Open ResEdit, open the Animation stack, then create a new resource as "Icon" and not "Icon#", use the "Icon editor" to draw the icon picture to your liking, then copy it and paste it into the Animation stack ResEdit window, save the changes, quit ResEdit, open your own stack, create a new button and then double click on it, displaying the button's dialogue window, click on the "Icon" button, and choose the icon picture you created in ResEdit, then copy the script from the Animation stack's "Do It!" button into your new button and you're all set!! Good luck and have fun with this stack!
